PTERIDACEAE

BRAKE FAMILY

Alan R. Smith and Thomas Lemieux

Perennial, in soil or on or among rocks; rhizome creeping to erect, scaly
Leaves generally all ± alike (or of 2 kinds, fertile and sterile), generally < 50 cm, often < 25 cm; petiole generally thin, wiry, often dark, in transverse section with vascular strands generally 1–3, less often many in a circle; blade generally pinnate or ± palmate-pinnate (see Adiantum ), often 2 or more compound, lower surface often with glands, ± powdery exudate, hairs, or scales; segments round, oblong, fan-shaped, or otherwise, veins generally free
Sporangia in sori or not, marginal, submarginal, or along veins, sometimes covered by recurved, often modified segment margins (false indusia); true indusia 0; spores spheric, sides sometimes flat, scar with 3 radiating branches
Genera in family: ± 40 genera, 500 species: worldwide, especially dry areas. Definition of Cheilanthes and related genera problematic; traditional limits often untenable.

ASPIDOTIS

Plant in soil or rock crevices; rhizome short-creeping-decumbent, scales elongate-lanceolate, generally dark, sometimes with very narrow, lighter margin
Leaves ± alike or fertile and sterile slightly dissimilar; axes grooved, light to dark brown; blade 3–4-pinnate, ovate-triangular to 5-sided, glabrous, upper surface ± glossy; segments long, narrow, with a pointed, sterile tip
Sporangia in small clusters or continuous along margin; false indusia scarious, irregularly toothed
Species in genus: 4 species: generally w North America, also eastern Can, ± dry, mountainous areas
Etymology: (Greek: shield-bearer, from shield-like false indusia in A. californica )
.

Native

A. carlotta-halliae (W. H. Wagner & E.F. Gilbert) Lellinger

CARLOTTA HALL'S LACE FERN


Leaf 3-pinnate, 8–15(25) cm, leathery; leaflets pinnately dissected, segments narrowly lanceolate to triangular, teeth few
Sporangia: false indusia ± as wide as or wider than long, generally fused at bases, 3–5(7) per segment, with many coarse, irregular teeth or lobes
Chromosomes: 2n=120
Ecology: UNCOMMON. Generally serpentine slopes, crevices, outcrops
Elevation: 100–1400 m.
Bioregional distribution: Central Western California
Synonyms: Cheilanthes c-h. W. Wagner & E.F. Gilbert
A fertile hybrid between A. californica and A. densa ; sometimes backcrosses
Horticultural information: SHD, DRN, IRR: 7, 9, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24; DFCLT.
See the CNPS Inventory for information about endangerment and rarity.
